J Rheumatol:系统性硬化症超早期阶段微血管系统紊乱的证据

2017-05-30 xiangting MedSci原创

与SSc患者相似,VEDOSS患者已经出现内皮功能障碍的生物学特征。

这项研究旨在探讨超早期诊断的系统性硬化症(VEDOSS)是否已经存在循环标志物和体外微血管功能障碍的表现。

从55例系统性硬化症患者(SSc),25例VEDOSS患者和55例健康对照(HC)获得血清样品。通过ELISA测量血管内皮生长因子(VEGF)和可溶性神经蛋白-1(sNRP-1)的血清水平。培养和激活SSc、VEDOSS和HC血清的人类皮肤微血管内皮细胞。通过Western-blot分析NRP-1的蛋白表达,通过5'-溴脱氧尿苷测定细胞增殖,伤口愈合测定迁移能力和Matrigel测定毛细管样血管形成。

与HC相比,VEDOSS和SSc患者的血清VEGF水平升高(分别为p = 0.05和p = 0.003)。与对照组相比,VEDOSS和SSc患者sNRP-1的血清水平显著降低(分别为p = 0.012和p = 0.027)。用VEDOSS血清刺激的H-MVEC中NRP-1表达降低(p <0.001 vs HC)。与HC血清相比,用VEDOSS或SSc血清刺激的H-MVEC的增殖减少(分别为p = 0.015和p = 0.043)。与HC血清相比,用VEDOSS和SSc血清刺激的H-MVEC中伤口愈合受损(p均 <0.01)。与用HC血清刺激的细胞相比,用VEDOSS血清(p <0.01)和SSc血清(p <0.001)刺激的H-MVEC中毛细血管生成减少。

由此可见,与SSc患者相似,VEDOSS患者已经出现内皮功能障碍的生物学特征。数据表明,VEDOSS血清显著改变内皮细胞行为并损害微血管系统的血管生成潜力。
